Power chip resistors extend resistance range, voltage ratings

Corpus Christi, Tex.  TT electronics IRC Advanced Film Division has extended the resistance range and voltage rating of its high power surface-mount chip resistors. The SC-3 series resistors now feature resistance values up to 100 Kohms and voltage ratings up to 100 V.

The SC-3 series chip resistors feature resistance ranges from 1 ohm (Ω) to 100 KΩ, with a maximum voltage rating of 100 V and an absolute tolerance to ±1%. The resistor dissipates up to 3 watts at 70°C, and features a temperature coefficient of resistance (TCR) of ±100 ppm/°C. The operating temperature range is -55°C to 150°C.

The chip resistors feature leach-resistant 60/40 tin/lead or 100% matte tin over nickel plated wrap-around terminations. Custom specifications are available. These devices may replace bulky molded wirewound resistors in motor and laser drive circuits, inverters, medical electronics and automotive applications. They can also be used in power supply bleeders, series voltage drop resistors, pulse applications and voltage dividers.

Pricing: $0.25 each in quantities of 1,000.
Availability: Lead time is from stock to 10 weeks.
